CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Patent ApplicationNo. PCT/CN2021/124872, filed on Oct. 20, 2021, which claims the benefitof priority from Chinese Patent Application No. 202011131631.9, filed onOct. 21, 2020. The content of the aforementioned application, includingany intervening amendments thereto, is incorporated herein by referencein its entirety.

TECHNICAL FIELD

The present application relates to LED lamp assembling technique, andmore particularly to a device for automatically installing a lamp tubeof an intelligent LED lamp cap.

BACKGROUND

In the actual application, a lens is generally arranged outside a LEDlamp bead of a vehicle lamp cap to enhance the brightness of the LEDlamp cap and achieve a light-condensing effect, so as to allow for ahigher penetrability. In the actual assembling process, the LED lampbead is fixedly arranged on the heat sink base through a reflectionbowl. The heat sink base is provided with a groove for accommodating theLED lamp bead. The reflection bowl is fixedly arranged on the heat sinkbase through screws. A lead wire of the LED lamp bead passes through athrough hole on the heat sink base. After the installation of the LEDlamp cap and the heat sink base, the heat sink base is introduced intothe lamp tube of the lamp cap to realize the connection between the heatsink base and the lamp tube. An end of the lamp tube is provided with alens to form the LED lamp cap. The LED lamp cap can be installed in thevehicle headlight for actual use. Nevertheless, the assembly of the LEDlamp cap is usually performed manually, resulting in a poor assemblingefficiency. Moreover, after the lead wire of the LED lamp bead passesthrough the through hole on the heat sink base, the LED lamp bead isprone to be separated from the lead wire when the lead wire is drawn byan external force, resulting in the scrap of the lamp cap.

To guide the heat sink base, the first feeding device 10 includes afirst vibration plate 11. An outlet of the first vibration plate isprovided with a first lead-out rail 11. An outlet of the first lead-outrail 11 is provided with an extraction rack 12. The extraction rack 12is arranged on a turnover mechanism. The turnover mechanism isconfigured to drive the extraction rack 12 to rotate by 180°, where arotation axis of the extraction rack 12 is arranged horizontally. Thefifth feeding device 50 is arranged on one side of the extraction rack12, and the fourth feeding device 40 is arranged on the other side ofthe extraction rack 12.

The heat sink bases are distributed in the first vibration plate.

Amounting surface of the heat sink base for mounting the LED lamp wick isconfigured to face downward. An axis of the heat sink base ishorizontal. The extraction rack 12 is configured to implement theplug-in feeding of the heat sink base. The turnover mechanism is turnedon to rotate the heat sink base by 180°, such that the mounting surfaceof the heat sink base for mounting the LED wick faces upwards,facilitating the assembly of the LED lamp wick.

In this embodiment, the extraction rack 12 is provided with twoextraction rods 121. The two extraction rods 121 are arrangedhorizontally and spaced apart. The two extraction rods 121 areconfigured to move horizontally to respectively be in plug-in clampingfit with two notches on the heat sink base. The outlet of the firstlead-out rail 11 is provided with a baffle plate 111. A surface of thefirst lead-out rail 11 is provided with two avoiding openings 112, inwhich the two avoiding openings 112 are configured to avoid the twoextraction rods 121.

One end of the returnspring 123 abuts against the extraction rod 121, and the other end ofthe return spring 123 abuts against the extraction rack 12. Theextraction rack 12 is provided with a first cylinder 124. The firstcylinder 124 is arranged in parallel with the two extraction rods 121. Apiston rod of the first cylinder 124 is connected to the two extractionrods 121.

When the heat sink base is taken by the extraction rack 12, the turnovermechanism is started to drive the extraction rack 12 to turn over, andthe two extraction rods 121 respectively form a plug-in fit with the twonotches on the heat sink base to allow the two extraction rods 121 toabut against the two notches to implement the picking operation. Theturnover mechanism is overturned, such that a mounting surface of theheat sink base faces upwards, facilitating the assembly of the LED lampwick and the heat sink base. Specifically, the two extraction rods 121respectively pass through the avoiding openings 112 and turn to the twonotches of the heat sink base to be inserted into the two notchesthrough the return spring 123, thereby realizing the picking operationof the heat sink base.

In this embodiment, the turnover mechanism includes a turnover base 13.The turnover base 13 is rotatably connected with two avoiding openings112.
